Indium(<scp>i</scp>)-catalyzed alkyl–allyl coupling between ethers and an allylborane

Abstract

An efficient method for alkyl-allyl cross-coupling between ethers and a 9-BBN-derived allylborane catalyzed by indium(I) triflate has been developed. The allylborane proved to be essential to obtain the desired products in high yields. The reaction displayed good substrate scope including high functional group tolerance.
